[next-20190530] Boot failure on PowerPC

[Lili Deng (Wicresoft North America Ltd)]

ACK for ' but it fixes the get_swap_device warning messages during the boot.'
Double check for kernel panic issue, without this patch, it seems not repro in my local manual environment, so please ignore my previous mail for 'the patch fixes the kernel panic'.
Sorry for the confusion.

Hi Sachin,

I verified below patch against Ubuntu 18.04, didn't hit the kernel panic any more, could you please let know how did you verify?

Thanks,
Lili

It does not help fix the kernel panic issue, but it fixes the get_swap_device warning messages during the boot.

Thanks
